Abstract: 837,654. Sewing machines. INDUSTRIEWERKE KARLSRUHE A.G. Dec. 20, 1957 [Feb. 16, 1957], No. 39712/57. Class 112 In a sewing machine roller feed drive the upper roller and means for imparting intermittent movement thereto are vertically displaceable in a common carrier under the differential action of two springs, one of which wholly or partly counterbalances the vertically displaceable parts. A shaft 9 journalled in a casing 8 is driven step-by-step by a one-way clutch 7 connected adjustably by a slotted crank arm 6 and a pitman 4 to a crank 3 on the machine arm shaft 2. Shaft 9 carries a belt pulley 10. Casing 8 is adjustably clamped to two vertical rods 11, 12 slidable in a carrier 18 secured behind the head 17 of the machine. Journalled in a support 19 fixed to the lower ends of said rods is a shaft 22 which carries a pulley 23 connected by a belt 25 to pulley 10, and also carries the toothed upper feed roller 24 which co-operates with the toothed lower feed roller 28 journalled beneath the work table 26. Housed in the hollow upper end of rod 11 is a spring 32 the force of which is adjustable by means of a nut 34 and which biases the rods downwardly. A spring 35 coiled about rod 12 and interposed between an arm 36 of carrier 18 and a collar 37 adjustably fixed to rod 12, biases the rods upwardly.

Filed: 1976-09-24
Abstract: 1527167 Data storage TELEFONAKTIEBOLAGET LM ERICSSON 24 Sept 1976 [29 Sept 1975] 39859/76 Heading G4A The clocking of data through a series of registers is checked by monitoring the propagation of a marker bit through a chain of bistables, one bistable for each register, the absence of one or more clock signals preventing the marker bit from propagating through the chain. The bistables may be spare stages in the registers. The marker bit is preferably inserted and repropagated through the chain after each successful propagation. The position of a fault may be localized by monitoring the propagation of a marker bit through each of a number of series connected blocks of registers and, after detecting a fault, monitoring the marker bit propagation within the block of registers containing the fault. Data flow through the registers may also be subject to a parity check.

Abstract: 1,241,576. Removing nitric oxide from waste gases. MITSUBISHI JUKOGYO K.K. and UBE INDUSTRIES Ltd. 23 Aug., 1968 [24 Aug., 1967], No. 40371/68. Heading C1A. A method of treating a waste gas containing NO comprises providing a further gas having a high content of NO 2 , admitting the waste gas and a first portion of the further gas to a first inlet of an absorber containing an alkaline absorbent solution, and admitting at least one further portion of the further gas to at least one further inlet of the absorber downstream of the first inlet. Suitable absorbents are caustic soda, sodium carbonate, calcium hydroxide, ammonia and ammonium carbonate, and the ratio of NO 2  to NO in the absorber is preferably 1: 1 or more by volume, the absorption product then being the corresponding nitrite. The further gas rich in NO 2  may be provided by separating a portion of the waste gas and oxidizing its NO content to NO 2  using oxygen present in the waste gas or added air or oxygen, and using an active carbon or silica gel catalyst if required. Alternatively when used to treat the waste gases from the production of nitric acid by the absorption of ammonia oxidation products, a portion of the ammonia oxidation products may be passed to a tank where, on standing, the NO content is oxidized to NO 2  to produce the further gas rich in NO 2 . In a third alternative method, the further gas rich in NO 2  is produced by treating the ammonium nitrite solution formed by absorption of the NO/NO 2  mixture with nitric or sulphuric acid in the presence of oxygen.

[Also in Groups VI and XXXVI] A percolator vessel 11 has a handle 12 with a passage through which an electric plug 61 enters a socket 41 nesting in the passage and forming part of a housing 40 connected by a tube 22 to a closed container 21 for a highwattage heating element 16. The plug 61 has an enlargement (not shown) so that it cannot pass completely through the handle and is disengaged when the housing 40 is removed. A spring-loaded pawl 43 prevents plug insertion in the handle unless the housing 40 is fully inserted therein and depresses the pawl. The container 21 houses both a thermostat T1 which cuts out the element 16 at the end of a brewing cycle, and a thermostat (not shown) which on overheating cuts out both the element 16 and a low wattage element 17 in parallel with the members 16, T1 and normally continuing to act after brewing to maintain brew heat. A pilot light P is in shunt with the thermostat T1. A pump well 23 has a dished cover 72 with entry apertures (not shown) controlled by a loose plate 71, and an exit pipe 70 to a coffee grounds basket 75 with a spreader plate 76. A lid of glass 83 and resilient plastic 82 has a pouring cut-out 88 and retaining bosses (not shown) which spring past the vessel neck 87.

Title: Resistance welding
Inventor: WALLACE JOHN FREDERICK
IPC: B23K11/25
Filed: 1964-10-08
Abstract: 1,109,180. Resistance welding. PRESSED STEEL FISHER Ltd. 7 Jan., 1966 [8 Oct., 1964], No. 41029/64. Heading H2H. [Also in Division B3] In a resistance spot welding circuit means dependent on expulsion of fused metal from the weld nugget are used to terminate the weld. In one arrangement a circuit detecting a sudden voltage drop across the welding electrodes terminates the weld. The electrode voltage is fed to a low pass filter and rectifier having a capacitor (not shown) across its output. The periodic charging of this capacitor drives two circuits each producing a series of square waves, one the converse of the other which together supply a continuous voltage to a gate element a. When expulsion occurs the reduction of voltage across the electrodes causes cessation of pulses from one circuit hence a "lock in " bi-stable circuit is triggered causing cessation of the welding current. An inrush protection circuit prevents operation of the gate element for the first two mains cycles. A pulse counting circuit also terminates the welding current after 32 cycles and gives a warning if expulsion does not occur within this period. This circuit also resets the welding circuit ready for another cycle. Expulsion may be alternatively detected by a strain gauge representing stress mounted on the electrode holding arms, or by a device sensitive to electrode movement. Current change may be also used as the terminating parameter.

Abstract: 1357584 Signalling over telephone circuits J R SHULL (Hotel Systems Corp) 7 Sept 1971 41634/71 Heading H4K In a hotel telephone system having an operator's substation 11 and a plurality of room extensions, such as 33, each connected by an individual line to the substation, the same lines are used for conveying signals relating to room status, e.g. vacant, being cleaned, occupied &c., to a front desk clerk and a housekeepers positions. During signalling the line 13 is disconnected from the substation by operation of change-over contacts 31a, 31b which is effected by the energization of relay coil 31c in response to closure of switch 20a by the desk clerk. A visual indication of this condition, which corresponds to room empty, is provided by illumination of red lamps 18a, 22a individual to the room on the clerk and housekeepers display panels. A maid on entering the room removes the handset thereby looping the line and bring- ing up relay 35 followed by 32. Her presence in the room is then indicated by intermittent illumination of green lamps 19a, 23a. (Contact 29 is operated intermittently by motor driven cam 28 so as to provide flashing illumination). When the maid replaces the handset, relay 35 falls back so as to cause the green lamps to burn continuously. The clerk having noted the room status restores switch 20a so as to release 31 and 32. In the event that the room has not been permanently vacated, the maid calls the front desk to apprise the clerk of her presence, the clerk operates switch 20a and all the relays come up to flash lamps 19a, 23a. Switch 20a is immediately restored so that when the handset is subsequently replaced, the relays release and normal telephone service is resumed. The relays may be energized by rectified A.C. rather than the mains supply shown connected to terminals 25, 26.

Air and condensed steam are removed from the mould during the filling and cooling steps respectively through the passages 20 and chamber 18 by a suction pump, which is also operated while the mould is opened to hold the article against the ejector means. Steam is supplied to the mould cavity through the inlet 32, chamber 18 and passages 20, and compressed air is similarly supplied to eject the article subsequent to opening the mould.
